... It?s official. б NASA?s Fermi Gamma-ray Space Telescope has found evidence that supernova remnants speed up cosmic rays to extremely high speeds. ... Amazingly, physicist Enrico Fermi postulated in 1949 that high speed cosmic rays were sped up in the magnetic fields of interstellar gas clouds. б Since then, scientists have focused on supernova remnants as a possible candidate for this process. Over 60 years later, the Fermi Gamma-ray Space Telescope has proven Enrico Fermi?s thinking to be true. ...

This image, taken 24 hours after the previous image, shows the supernova to be another 0.21mag (or about 25%) brighter. ... Hopefully the images do show that the brightness of the Supernova is changing. ...

We investigate the dust associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC) as observed with the Herschel Space Observatory. N49 is unusually bright because of an interaction with a molecular cloud along its eastern edge. We have used PACS and SPIRE to measure the far IR flux densities of the entire SNR and of a bright region on the eastern edge of the SNR where the SNR shock is encountering the molecular cloud. ...
